The New Dimensions of Nike Free

Building upon over a decade of Nike Free innovation, Nike unveils new additions to its Free footwear family. Each features a progressive geometric auxetic midsole designed to enable an athlete’s natural motion and develop strength, whether they are running or training.

Drawing upon new studies that reveal how the foot expands and contracts upon impact with and liftoff from the ground, the splaying, auxetic midsole mimics how the body and foot react to force. It absorbs shock while accounting for the dual-plane expansion in foot size — approximately one size in length and two sizes in width — that occurs throughout an athlete’s foot strike.

Moreover, the multi-directional outsole flexibility closely mimics this changing shape, whether an athlete is moving linearly in running or multi-directionally in training. The resulting flexibility puts the foot, rather than the shoe, in control. Or, as explained by three-time gold medal sprinter Allyson Felix, "Using Nike Free footwear in my training is all about strengthening my feet. I really like having that natural movement in my shoes. Everyone’s feet are different, so it’s great to have a shoe that really moves with you."

RUNNING

Every runner possesses a one-of-a-kind stride, defined by his or her respective gait and physique.

The zonally engineered, lightweight Flyknit upper combines a sock-like fit with a classic silhouette that molds to the foot. The midsole features the same expansive auxetic technology with a brand new, softer IU foam for additional underfoot comfort.

TRAINING

The ways an athlete trains are as varied as the reasons why. They run, jump, cut and lift, requiring varying degrees of support and flexibility.
